Facestock
The visible paper or film layer that carries the printed graphics and provides the label’s appearance and physical properties.
Label Materials and Adhesives
The right label construction depends on more than appearance. Facestock, adhesive, liner, printing method, protective finish, application surface, and environmental exposure all affect how a label performs.
Minnesota Label helps match materials and adhesives to product packaging, containers, equipment, inventory, manufacturing applications, and demanding operating environments.
- Paper and film label materials
- Permanent and removable adhesives
- Options for moisture, abrasion, chemicals, and temperature
- Custom constructions for specific surfaces and applications
Choosing a Complete Label Construction
A pressure-sensitive label is a layered construction. Each component should work with the others and with the final application.
Adhesive
The pressure-sensitive layer selected to bond with the application surface under the expected conditions.
Release Liner
The backing that protects the adhesive until application and supports dispensing, converting, and die cutting.
Ink and Imaging
Printed graphics or variable information selected for the label material, application, and required durability.
Protective Finish
A coating or laminate may be used to help protect graphics from moisture, abrasion, handling, or chemical contact.
Finished Format
Roll direction, core size, maximum roll diameter, spacing, and winding affect hand and machine application.
These components can be combined into custom pressure-sensitive label constructions for a wide range of products and operations.
Paper Label Materials
Paper facestocks are practical for many product, packaging, identification, and indoor applications. They are available in different appearances and can be paired with adhesives and finishes based on the project requirements.
Coated Paper
Provides a smooth printing surface for branded graphics, product information, and general-purpose labels.
Uncoated Paper
Offers a natural paper appearance and may be suitable when writing, stamping, or a less glossy finish is desired.
Textured Paper
Creates a distinctive visual and tactile appearance for selected product and packaging applications.
Fluorescent and Specialty Paper
Supports warning, identification, promotional, and other applications requiring high visibility or a specialized appearance.
Paper generally performs best in controlled conditions unless it is paired with an appropriate protective finish and adhesive. Film may be a better choice when moisture, tearing, or demanding exposure is expected.
Film Label Materials
Film facestocks can provide flexibility, moisture resistance, tear resistance, and durability beyond typical paper constructions. The correct film depends on the container, appearance, exposure, and application method.
Polypropylene
A versatile film used for many product and packaging labels where moisture resistance and a clean appearance are important.
Polyester
A durable film often considered for industrial, identification, equipment, and other demanding label applications.
Polyethylene
A flexible film that can conform to certain squeezable, curved, or flexible containers and surfaces.
Clear Film
Allows the product or container to remain visible and can support a clean, minimal label appearance.
White Film
Provides an opaque base for color graphics, text, product identification, and branded packaging.
Metallized Film
Provides a metallic visual effect for selected branding, promotional, identification, and decorative applications.
Label Adhesive Options
Adhesive performance is influenced by the surface, application temperature, service temperature, dwell time, exposure, and label construction. An adhesive that works on one package may not perform the same way on another.
Permanent Adhesives
Designed to build a lasting bond when the label is expected to remain attached throughout its intended use.
Removable Adhesives
Designed for selected temporary applications where the label should be removed under defined conditions.
Repositionable Adhesives
May allow limited adjustment during application before the adhesive develops its intended bond.
Freezer and Cold-Temperature Adhesives
Selected for projects involving refrigerated products, frozen storage, or application at reduced temperatures.
High-Tack Adhesives
Considered for selected difficult, rough, textured, or low-surface-energy applications requiring aggressive initial adhesion.
Special-Purpose Adhesives
Custom requirements may call for adhesives designed for specific surfaces, temperatures, environmental exposures, or planned service conditions.
Surface Conditions That Affect Adhesion
Adhesive selection begins with the actual surface receiving the label. Surface material and condition can significantly affect initial tack and long-term bond.
- Glass, metal, paperboard, and corrugated packaging
- Rigid and flexible plastic containers
- High- and low-surface-energy plastics
- Smooth, rough, textured, or powder-coated surfaces
- Flat, curved, irregular, or squeezable containers
- Clean, dry, dusty, oily, or contaminated surfaces
- New, recycled, painted, or treated materials
Whenever possible, identify the exact substrate rather than describing it only as “plastic,” “metal,” or “cardboard.” Different versions of the same general material can behave differently.
Application Temperature vs. Service Temperature
Application Temperature
The temperature of the label, adhesive, and surface when the label is first applied. This affects the adhesive’s ability to wet out and begin forming a bond.
Service Temperature
The temperature range the applied label experiences after the adhesive has formed its intended bond.
These temperatures are not interchangeable. A label may tolerate a cold service environment after application but still require application above a specified minimum temperature.
Environmental and Performance Considerations
The expected environment helps determine whether the project requires paper or film, a specialized adhesive, protective finishing, or application testing.
| Project factor | Questions to consider |
|---|---|
| Moisture | Will the label encounter condensation, refrigeration, water, washing, or prolonged humidity? |
| Temperature | What are the application, storage, transportation, and service temperatures? |
| Abrasion | Will the label experience rubbing, repeated handling, shipping, scraping, or equipment contact? |
| Chemicals | Could the label contact cleaners, oils, solvents, ingredients, fuels, or process chemicals? |
| Outdoor exposure | Will the label encounter sunlight, UV exposure, rain, snow, or changing temperatures? |
| Expected lifespan | Must the label last through temporary use, distribution, product life, or long-term equipment service? |
| Container movement | Will the container flex, squeeze, expand, contract, or bend after application? |
| Regulatory information | Must specific instructions, warnings, identification, or product information remain readable? |
Protective Label Finishes
A coating or laminate can help protect printed graphics, but it does not replace correct facestock and adhesive selection. Finishing should be considered as part of the complete construction.
Protective Coatings
A coating can provide a finished appearance and help protect printed graphics from ordinary handling and selected environmental exposure.
Overlaminates
A clear film layer can provide added protection against moisture, abrasion, handling, and selected chemicals.
Gloss and Matte Finishes
Finish selection affects appearance, glare, texture, and how the label coordinates with the package or product.
Materials for Different Label Applications
Food and Beverage Labels
Consider container material, refrigeration, condensation, packaging appearance, handling, and distribution.
Industrial Labels
Evaluate abrasion, chemicals, temperature, equipment surfaces, outdoor use, and required service life.
Barcode Labels
Match material, imaging method, finish, and adhesive to scanning, handling, and environmental requirements.
Blank Labels
Select printable facestocks and adhesives compatible with the intended printer, ribbon, surface, and environment.
Warehouse Labels
Consider shelving, bins, pallets, floors, handling, scanning distance, and temperature conditions.
Consumer Product Labels
Balance package appearance with moisture, handling, container shape, product contact, and retail conditions.

Physical samples, photographs, containers, or pieces of the application surface may help when a project involves unusual materials or difficult conditions.
Material Testing and Application Trials
Published material specifications help narrow the options, but they cannot represent every combination of surface condition, temperature, contamination, exposure, and application process.
Testing may be appropriate when labels will be applied to textured surfaces, low-surface-energy plastics, tight curves, flexible containers, cold products, contaminated surfaces, or environments involving chemicals and moisture.
-
Use the Actual Surface
Test on the same material, coating, texture, and container shape used in production.
-
Replicate Application Conditions
Apply the sample at the expected temperature and under realistic cleanliness and handling conditions.
-
Allow Bond Development
Evaluate performance after the adhesive has had appropriate time to build its bond.
-
Reproduce Service Exposure
Test moisture, refrigeration, flexing, abrasion, chemicals, or temperature changes that the label may experience.
Printing Options for Your Label Construction
Once the construction is established, the printing process can be selected based on quantities, number of designs, artwork stability, material compatibility, and repeat-order needs.

Label Materials and Adhesives FAQ
How do I choose a label material?
Select the material based on the application surface, desired appearance, printing method, environmental exposure, expected lifespan, and application process. Paper is practical for many controlled applications, while film is often considered for additional moisture resistance, flexibility, tear resistance, or durability.
What is the difference between paper and film labels?
Paper is a practical choice for many indoor and controlled applications. Film materials generally provide greater resistance to moisture, tearing, abrasion, chemicals, and changing environmental conditions.
What is the difference between permanent and removable adhesive?
Permanent adhesives are designed to build a lasting bond. Removable adhesives are designed for selected temporary applications where planned removal is required. Actual removability depends on the adhesive, surface, time, temperature, and exposure.
Why does application temperature matter?
Application temperature is the temperature of the label and surface when the label is first applied. Applying a label outside the adhesive’s recommended range can prevent it from forming the intended bond.
Can labels adhere to textured or curved surfaces?
Labels can be designed for many textured or curved surfaces, but the surface material, texture, radius, label size, facestock flexibility, and adhesive must be evaluated together. Testing may be recommended.
Can Minnesota Label help test a label construction?
Minnesota Label can help evaluate project requirements and determine whether application testing or material samples should be considered before full production.
